The plurality of first cooling plates 18 and the plurality of second cooling plates 19 are spaced apart along the length direction of the connecting groove 17. The spaced apart distribution prolongs the time that the gas stays in the connecting groove 17, and at the same time, the first cooling plates 18 and the second cooling plates 19 cool the gas more fully.

[0025] like Figure 4As shown, the air intake assembly 11 includes an air outlet pipe 20, one end of the air outlet pipe 20 is connected to the connecting groove 17, the other end of the air outlet pipe 20 is connected to the pipe elbow 21, the end of the elbow 21 away from the air outlet pipe 20 is connected to the air supply pipe 22, the other end of the air supply pipe 22 is connected to the connecting pipe 23, the end of the connecting pipe 23 away from the air supply pipe 22 is connected to the lower template 9, and the gas after cooling is completed passes through the air outlet pipe 20, the elbow 21, the air supply pipe 22 and the connecting pipe 23 in turn into the lower template 9.

[0030] Working principle: The supercharger 13 drives the air flow in the equipment, and the external air enters the filter assembly 15 through the air inlet pipe 14. The filter plate 31 dries and removes impurities from the external air. The dried and impurity-removed gas and the gas in the chamber 2 enter the cooling mechanism 10 through the return air pipe 12. The first cooling plate 18 and the second cooling plate 19 in the cooling mechanism 10 fully cool the gas in the connecting groove 17. The cooled gas enters the lower template 9 through the air outlet pipe 20, the elbow 21, the air supply pipe 22 and the connecting pipe 23 in turn. The cooled gas enters the chamber 2 along the buffer groove 24, the through groove 25, the groove 26 and the air outlet groove 27.
